however not update textbox? should doing differentely?

what im doing wrong ? how can correctly have looked @ several article on here have not been successful @ of them. great appreciated.

i'm not sure if that's case, in:
form1.mytext = userpicked.tuid
you're refering newly created form1 object, initialized 1 line above. if you'll check form1.mytext property, you'll notice has value assigned, it's not form object want refer to. if textboxes in form2, create form2 reference in form1. private form2 form2 = null;
, create property

public form2 secondform { set { this.form2 = value; } } assign , use form2.tuidinput.text in form1 normally.
